Connectivity Service Platform Subscription Fall-back Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connectivity service platforms face difficulties in falling back to an alternate subscription when connection is lost with a radio device, as they lack an active secondary subscription to facilitate this transition.
Innovation Solution
The platform receives a request message with a fall-back attribute, allowing it to activate a secondary subscription, enabling communication with the radio device and ensuring network connectivity is restored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connectivity service platform loses connection with the radio device via the second subscription, then it cannot activate the secondary subscription for fall-back, but it needs to fall back to an alternate subscription to restore connectivity
Solution Approach 1:
The platform stores subscription information (including the second subscription) in advance in its database before connection is lost. When a fall-back request is received, the platform can immediately activate the pre-stored second subscription without needing to contact the device first, thus resolving the contradiction between maintaining reliability and enabling easy operation.
2Reliability
If the platform contacts the device to obtain information about the currently active subscription, then it can enable fall-back to the same subscription, but it cannot contact the device when connection is lost
Solution Approach 1:
The platform performs preliminary actions by storing the device's subscription information (IMSI, authentication data, etc.) in its database during normal operation before any connection loss occurs. This allows the platform to immediately activate the correct subscription when fall-back is needed, without requiring real-time communication with the device, thus ensuring both reliability and fast productivity.
Solution Approach 2:
The platform's database acts as an intermediary that stores and manages subscription information. Instead of directly contacting the device to obtain subscription details, the platform retrieves this information from its stored database, eliminating the need for real-time device contact while ensuring accurate subscription activation.
3Reliability
If the platform activates the second subscription without receiving a request message with fall-back attribute, then it may waste resources, but it needs to respond quickly to fall-back requests
Solution Approach 1:
The platform uses the fall-back attribute in the request message as feedback to determine whether activation is needed. The attribute acts as a signal that confirms the device has lost connection and requires fall-back, allowing the platform to activate the second subscription only when necessary, thus avoiding wasted resources while maintaining fast response to legitimate fall-back requests.

AI summary
The present disclosure relates to a method performed by a connectivity service platform (2) in a communication network (1). The method comprises receiving a request message (9) from a radio device (5) via a wireless network connection of a second subscription of the radio device. The method also comprises observing that the connectivity service platform is not enabled to communicate with the radio device via the wireless network connection of the second subscription. The method also comprises determining that the received request message is associated with a fall-back attribute. The method also comprises activating the second subscription in the connectivity service platform in response to the received request message, thereby enabling the connectivity service platform to communicate with the radio device via the wireless network connection of said second subscription of the radio device.
